Leech Seed is a long-running Grass-type move in the Pokémon video games, first introduced in the original generation, where it plants seeds on an opponent and restores the user's health as the opponent loses it each turn. The distinctive sound has become familiar through years of battles, remakes and gameplay footage shared online, and soundboard users now reuse it beyond Pokémon itself as a shorthand for slow draining, leeching or a trap taking hold. Its staying power comes from that clear, game-born association rather than any single viral moment.
